General features

Measuring module MPT-3p is a component of the Ampio Smart Home system and is designed to connect PT1000 sensors.

Sometimes there is a need to connect the temperature measuring points exceeding the measuring range of digital Dallas sensors. It can take place on the temperature control or monitoring of heating systems, e.g. a fireplace or the CO furnace. For this purpose we have created a device giving possibility of connecting platinum sensors,
characterized by a very large measuring range and very good accuracy and linearity in the range measurement (PT1000).

Module is controlled via CAN-Bus. Required voltage to power the module is 11-16V DC.

Thanks to module dimensions it can be fixed in a standard junction box with 60mm diameter.

Three device inputs enable connecting 3 PT1000 sensors.

Module is equipped with Light indicator that provides information about connection status:

  • one regular flash every 1 sec. – CAN-Bus communication in order
  • two regular flashes every 1 sec. – module is not receiving information from other SmartHome modules
  • three regular flashes every 1 sec. – module cannot send information to CAN-Bus


The module may be programmed with a special programmer, available for authorised technicians, and the Ampio SmartHome CAN configurator software. This program provides for setting up the module’s response to input signals and other information
from the CAN bus.
